Abstract: 1461986 Jointing CENTRAL GLASS CO Ltd 30 April 1975 [30 April 1974 31 Oct 1974] 18052/75 Heading B3V A heated strand 48 is adhered to a sheet 3 of a thermoplastic bonding agent by apparatus comprising a table 1 for the sheet and a strandsupply head 2 movable parallel to the supporting surface of the table, the head including a heater 32 for the strand and means 28 for pressing the heated strand against the sheet. As applied to making an automobile aerial antenna, the strand is of copper and is adhered to a sheet of polyvinyl butyral which is subsequently bonded between sheets of automobile window glass. The head 2 is traversed over the table 1 under control of a numerical control system, and a servomotor 18 is controlled to steer the strandpressing roller 28 in the direction of head progression. The roller is carried by a shaft 20 in bearings in a part 5 which is lowered, to apply the roller, by a solenoid 6 mounted on a part 4 of the head. Steering movements of the shaft 20 from the motor 18 are through gears 19, 17, 21. Corresponding movements are transmitted to a support box 10 for a reel 11 of the strand through gears 16, 8. A wire cutter 45a on a sleeve 22 mounted on bearings 23 on the shaft 20 and keyed thereto at 31, 32a is operated against a return spring 44 by a solenoid 39. An arm 26, 34 on the solenoid plunger 41 is guided by pins 35, 36 and mounts a roll (not shown) lodged between flanges 24, 25 on the sleeve 22. The combined pressing unit and wire cutter need not be steered if a non-rotatable presser 50, Fig. 2, is used which is surrounded by an annular cutter 54. In a further construction, Fig. 3 and Figs. 4 and 5 (not shown), in which the presser roll 141 and a shear blade 181 are steerable by a motor 116, drive from the motor is through gears 117, 118, 121, 122 to a rotatable carrier 114 from the bottom of which the roller is suspended in a crosshead 135 also carrying the heater 138 which is supplied through thrust bearings 147, 148. A rod 161 with axial grooves 166, 168 and a lateral passage 167 is threaded with strand before being inserted in the thrust bearing unit and in the carrier 114, the strand being led between the roll 141 and a spring-biased presser roll 186, Fig. 3 and Fig. 5 (not shown). The thrust bearing unit and the rotary carrier 114 are mounted on a plate 118 which is lowered, against a bias of a spring, by a rotary solenoid (111) to press the strand against the sheet 103. The shear blade 181 is operated, through a lever (171), a collar 169 and a rod 179, by a rotary solenoid (176), a spring 145 effecting return movements. When there is no strand on the supply reel 163, a member (191) operates a microswitch (192) and a lamp (196) is illuminated.

Abstract: 562,338. Straight-line motions; conveying circular motion. BUTLER, F. G. J., and KITE, E. A. Dec. 22, 1942. No. 18165. [Class 80 (iii)] A straight-line linkage comprises a link CB pivoted to a fixed point C at the intersection of lines X-X<1>, Y-Y<1>, this link being pivoted to a lever BA, a point D in which is connected by a long link DE to a pivot E fixed on the line X-X<1>. To obtain the position of E, a point K is taken about one-quarter of the length of the link BC from B and with centre C an arc is struck cutting X-X<1> at F. The point D is taken at one quarter of the length of lever AB from B. The arc or line joining the points D, F is bisected at right-angles by a line H-H<1> which, produced downwards intersects X-X<1> at E. With the linkage described, the point A moves along the line Y-Y<1> over a considerable range. In a modification, motion may also be obtained along the line X-X<1> by extending the lever AB. In a further modification, Fig. 7, two points of support are provided for the element to be moved by prolonging the link DE to a point T and connecting T with A by two links TL, LA similar to TD, DA but oppositely disposed. In a still further modification, Fig. 9, a shaft M with crank-pin A is to drive a shaft C at half speed. The shaft C carries a disc P in which, previously, there has been a groove along Y-Y<1> to accommodate a roller on crank-pin A. According to the invention, instead of the groove, linkwork is employed, the crank-pin A being the equivalent of the point A, Fig. 1, and the pivot E is on a line X-X<1> on the disc P. Hence A moves along Y-Y<1>. The throw of the crank is equal to the eccentricity of the shafts.

Title: Improvements in or relating to the heat treatment of hardenable ferrous metal articles
IPC: C21D9/32
Filed: 1948-07-09
Abstract: Ferrous metal articles are surface hardened by subjecting them to an electromagnetic field of a first frequency, then to an electromagnetic field of a second frequency, the second field being of a higher frequency than the first, of such conformation and frequency and for such a time that a shallow austenitic layer is formed on selected portions only, and then quenching the article.  As shown, for the surface hardening of gear wheels, a plurality of work holders 21 carrying quenching rings 25 and locating means are moved intermittently along a track by a dog 321 operated by an air cylinder 33.  A gear wheel 20 supported in a carrier moves first through a series of preheating stations 1-4 each having an induction coil 40 supplied with current from an audio frequency generator 41.  It then moves to a station 5 which has a coil supplied from a radio frequency generator 43, where the surface is heated to a temperature above the transformation temperature and is given a preliminary quench immediately after the required temperature has been attained-the quench should be within 0.5 second from the attainment of the temperature.  Further quenching is carried out at station 6 from which the gear passes to stations 7, 8, and 9 each of which has a coil supplied from the audio frequency generator, where the hardened surface is tempered.  An air operated cylinder 60 discharges the treated gear.  The base plate of the carriers 21 has an aperture, and at each station a spindle passes through this aperture and lifts and rotates the gear during its stay at that station.  The preheating and reheating may be applied for 4 seconds, the radio frequency heating for 0.4 to 1 second, the preliminary quench for 3 seconds and the movement from station to station may take 2 seconds.  The audio frequency may be from 900-15,000 cycles per second and the radio frequency 90-450 kilocycles per second.  Alternatively two different audio frequencies or two different radio frequencies may be used.
